Ultramarines: The Ultramarines are the classical Space Marines chapter. Following the doctrine of the Codex to the letter, they are a strictly organised chapter with an excellent gene-seed. For this reason they have been the source of many Second Founding chapters. According to the Apocrypha of Davio there are 8 Second Founding chapters who originate from the Ultramarines gene-seed. The Apocrypha of Skaros claims there are as many as 23 chapters, but does not go so far as to name them.
